1. Resistive conductors tend to heat up when current flows through them. The temperature of the conductor typically depends on the amount of current it carries, where a higher current leads to a higher temperature. Additionally, the resistivity of a metallic conductor increases with increasing temperature. Therefore, the resistance of a piece of metal will generally increase if the current in the metal increases. This effect is usually negligible if the temperature of a circuit element does not vary too much during its operation. However, this effect can be significant in circuit elements that experience large temperature variations, like incandescent light bulbs and the heating elements in a toaster. The main component in an incandescent light bulb is a coiled filament of tungsten that is 580 mm long with a diameter of 46 µm. At 20°C, tungsten has a resistivity of 5.25 × 10-8 · m. Its temperature coefficient of resistivity is 0.0045 (Cº)-1, and this remains accurate even at high…
